The gender pay gap at labour market entrance: Evidence from Germany

The authors investigate wage differentials between German male and female graduates at labour market entrance at all percentiles of the wage distribution. The wage differentials are decomposed using the single‐index approach suggested by DiNardo, Fortin and Lemieux (1996) and Fortin and Lemieux (1998), and by endowment, price and returns‐to‐skill function effects. The results reveal higher starting salaries for men at all percentiles of the income distribution, with the pay gap varying in magnitude. The endowment and price effects are favourable for men throughout. The effect of the difference in the returns‐to‐skill function works in favour of female graduates.     

Native‐Migrant Wage Differential Across Occupations: Evidence from Australia

We investigate wage differential by migrant status across white‐collar and blue‐collar occupations in Australia. Migrants are observed to have a higher wage; this difference, however, does not exist once we control for covariates. The unconditional wage differential varies over wage distribution as well as by occupation. Significant wage differentials are found above the median: positive for white‐collar workers and negative for blue‐collar workers. Using recently developed decomposition methods based on Firpo, Fortin, and Lemieux (2009) we decompose wage differentials across their distribution. Overall, the wage advantage of migrants reflects their superior labour market characteristics, and in particular, their levels of education. We find that English language proficiency plays an important role in wage differences among immigrants from non‐English speaking countries.     

Les différences de salaire au sein de l'Union européenne

Les auteurs recherchent les déterminants des écarts salariaux au sein de l'Union européenne selon la position dans la distribution des salaires, suivant en cela la méthode proposée par Firpo, Fortin et Lemieux (2009) et par Fortin, Lemieux et Firpo (2011). Ils expliquent ces écarts à la fois par un effet de composition et par un effet de structure. Ce dernier effet, plus puissant, dépend surtout des facteurs non observés, alors que l'effet de composition peut ětre attribué principalement au niveau de diplôme, à la profession, à la fréquence des fonctions d'encadrement et, dans une moindre mesure, au secteur d'activité.     

Écart salarial entre hommes et femmes au début de la vie active: mise en évidence dans un exemple allemand

Les auteurs recherchent l'écart salarial entre hommes et femmes dans une population de jeunes diplômés allemands, y compris selon la position dans la distribution des salaires. Ils décomposent cet écart par la méthode à indice des compétences de DiNardo, Fortin et Lemieux (1996) et Fortin et Lemieux (1998), faisant la part entre effet de dotation, effet de prix et effet du rendement des compétences. L'analyse fait apparaître une prime salariale masculine systématique, mais plus ou moins marquée selon le quantile. En outre, les effets de dotation et de prix favorisent les hommes, annulant l'influence d'un effet du rendement des compétences favorable aux femmes.     

Racial wage differentials among young adults: Evidence from the 1990s

This study seeks to decompose wage differentials between black and white male young adults into those related to labor market discrimination and those resulting from human capital endowments. The importance of testing for significant differences in wage equations before conducting decomposition analysis is emphasized. Study results demonstrate that ignoring correction for the sample selection bias resulting from black-white differences in the probability of being employed would lead to an underestimation of the size of wage differentials. The study also shows that the results of models based on different assumptions regarding the nondiscriminatory wage structure might lead to different conclusions pertinent to the extent of labor market discrimination. Implications for public policy development are discussed.

Wage Decompositions with Selectivity-Corrected Wage Equations: A Methodological Note

This paper examines the implications of the standard Heckman (Heckit) correction for selectivity bias in wage and earnings functions that are subsequently used in wage decompositions. Even when justified, Heckit selectivity correction introduces some fundamental ambiguities in the context of wage decompositions. The ambiguities arise from group differences in the selection term which consists of a parameter multiplied by the Inverse Mills Ratio (IMR). The parameter is identified as the product of the standard deviation of the errors in the wage equation and the correlation between the wage equation error and the selection equation error. How should group differences in these parameters be interpreted in terms of structural differences and endowment effects? The same issue arises with respect to group differences in the IMR which reflect nonlinear group differences in the determinants of selection and in the probit coefficients.     

Union Worker Wage Effect in the Public Sector

This study examines union wage premiums in the public sector for the 1998–2004 period. Unlike previous studies, our approach estimates union wage premiums considering differences in the rewards to education, experience, and other personal characteristics for union and non-union workers. The approach provides a larger estimated wage gap than the traditional approach, and allows for simulations of union–nonunion wage gaps for different types of workers. Moreover, we use an Oaxaca decomposition to explain the larger union–nonunion wage gap in the private sector in comparison to that in the public sector. We find that between 50% and 60% of the difference in union wage premiums between the private and public sectors is due to differences in the way unionized workers are rewarded in the private and public sectors, while the remaining portion is due to differences in personal characteristics of private and public sector workers.

Wage Inequality and Performance in Nonprofit and For‐Profit Organizations

This article examines the effects of several forms of wage inequality on service quality and employee effort. We suggest that two popular theories, tournament and fair wage/equity, are not necessarily competing. Each theory accurately describes aspects of employee behavior, but because of sectoral differences in organizational objectives and employee attitudes, tournament theory's predictions are relatively stronger in the for‐profit sector, while fair wage/equity theory's predictions are relatively stronger in the nonprofit sector. Using an employer–employee matched data set of nursing homes linked to a federal regulatory database and a resident survey, we found that ownership moderates the relationship between wage inequality and service quality. Although wage inequality positively affects service quality in the for‐profit sector, the reverse is true among nonprofit organizations. We also found that overall wage inequality in the workplace has a more pronounced influence on employee discretionary effort than does the employee's place in the distribution of wages.     

The difference between wages and wage potentials: Earnings disadvantages of immigrants in Germany

Immigrants in Germany have poor earnings performance relative to natives. Claiming that human-capital endowments determine earnings potentials rather than actual earnings, a stochastic earnings frontier is estimated and used to seek systematic differences between natives and migrants for GSOEP data for the year 2000. While empirical results clearly support the frontier assumption, natives and immigrants are surprisingly about the same with respect to the frontier. Assuming a half-normal distribution of the wage gap, on average, both groups transform a modest 84% share of their potential income into market earnings. This implies wage inequality can be attributed to human-capital differentials alone. The human-capital endowments of immigrants are largely determined by the very low percentage who have college degrees, their slow assimilation and zero-return on imported experience. The paper also tries to explain individual wage gaps, which are significantly decreased in married subjects raising families, but increased in employees in small- or medium-sized relative to larger firms. However, these variables only make minor contributions to the variance.     

Minimum wages and poverty with income-sharing

Textbook analysis tells us that in a competitive labor market, the introduction of a minimum wage above the competitive equilibrium wage will cause unemployment. This paper makes three contributions to the basic theory of the minimum wage. First, we analyze the effects of a higher minimum wage in terms of poverty rather than in terms of unemployment. Second, we extend the standard textbook model to allow for income-sharing between employed and unemployed persons in society. Third, we extend the basic model to deal with income sharing within families. We find that there are situations in which a higher minimum wage raises poverty, others where it reduces poverty, and yet others in which poverty is unchanged. We characterize precisely how the poverty effect depends on four parameters: the degree of poverty aversion, the elasticity of labor demand, the ratio of the minimum wage to the poverty line, and the extent of income-sharing. Thus, shifting the perspective from unemployment to poverty leads to a considerable enrichment of the theory of the minimum wage.      

Two Components of Wage Gaps Induced by Individual-level Variables: Intra-firm or Inter-firm?

Individual-level variables such as gender, education, occupation, and employment type are well-known factors that induce wage gaps in the labor market. This article aims to divide wage gaps into two components—those arising within each firm (the intra-firm wage gap) and those arising between different firms (the inter-firm wage gap)—and measure their respective proportions by individual-level variables, as studies suggest that each wage gap based on an individual-level variable has a unique mix of an intra-firm and inter-firm wage gap. This measurement can help enrich investigation into the generative process of wage gaps and formulate effective labor policies to reduce them. Accordingly, we compared the coefficients of the independent variables of the wage function estimated by a pooled ordinary least squares model and a fixed-effect model, using nationwide employer–employee matching data collected by the Japanese government. We found that wage gaps by gender and employment type mostly consist of intra-firm wage gaps, and those by education and occupation have a larger share of inter-firm wage gaps. The findings suggest that different research strategies are required to investigate the generative process of each wage gap, and that regulations on and interventions in organizational processes are important to reduce wage gaps based on gender and employment type.     

Job-search Networks and Wage Attainment in China: A Comparison of Job Changers and Non-changers

This article examines job-search networks and entry-level wage attainment using data from a large-scale survey conducted in eight cities in China in 2009. Two key issues are addressed: (i) how the use of social networks is associated with entry-level wage attainment in urban China, and (ii) whether the patterns of network effects on entry-level wage differ between job changers and first-job seekers. The results show that both strength of ties and social resources of job-search networks are significantly associated with entry-level wage attainment, and that the network effects on entry-level wage are greater for job changers than for first-job seekers. This study offers a solid empirical verification of the associations of weak ties with information and strong ties with influence in an analysis of entry-level wages for job changers and first-job seekers.     

Wage distribution and firm size: The case of the United States

Substantial literature has been produced on the increasing wage gap in the United States, invoking various possible factors, but largely ignoring the relationship between firm size and wage distribution. In this study, the author decomposes wage differences over time between large, medium and small firms, identifying the effects of observed characteristics (and their returns) along with residual inequality, i.e. inequality among workers with the same observed characteristics. From 1992 to 2012, trends at small, medium and large firms became more uniform, while wage inequality rose across the board. Significantly, it increased more quickly in the upper half of the wage distribution and at large firms, where residual inequality was highest.     

Visualising Gender Wage Differences in the European Union

The purpose of this article is to illustrate differences in the gender wage gap in 13 EU member states, using figures taken from the Household Panel for 2000. The methodology is based primarily on the kernel density functions of men's and women's wages. A range of situations can be observed from the Mediterranean countries (with a smaller gender pay gap) to the very specific cases of Austria and the UK and to northern European countries where the gender pay gap is chiefly the result of a larger proportion of men at higher‐paid levels. We also offer conclusions on the relevance of public employment, part‐time employment and short‐term hiring to explain the gender wage gap in each of the countries studied.     

More wages,more income,more leisure? Evidence from Thailand’s time use survey

ABSTRACT

Does more income mean more leisure? This paper investigates the impact of wages and income on leisure time using merged data from two nationally representative samples in Thailand: (1) the Time Use Survey, and (2) the Labor Force Survey. Results will depend on our definition of income or wages. The data indicate that Thai people tend to reduce their leisure time in response to monthly income changes. The reason for such a negative relationship is that monthly income is composed of extra income other than wages, for example, overtime and bonus pay, which are found to be inversely related to leisure time. However, when the relationship between leisure time and hourly wage is estimated, we find that an increase in hourly wage substantially and significantly induces people to engage in more leisure and that a percentage change in hourly wage also provides a positive percentage change in leisure time.     

“Family-Friendly” Fringe Benefits and the Gender Wage Gap

Evidence suggests a large portion of the gender wage gap is explained by gender occupational segregation. A common hypothesis is that gender differences in preferences or abilities explain this segregation; women may prefer jobs that provide more “family-friendly” fringe benefits. Much of the research provides no direct evidence on gender differences in access to fringe benefits, nor how provision affects wages. Using data from the National Longitudinal Survey of Youth 1979, we find that women are more likely to receive family-friendly benefits, but not other types of fringe benefits. We find no evidence that the differences in fringe benefits explain the gender wage gap.

Fixing minimum wage levels in developing countries: Common failures and remedies

Some developing countries have set their minimum wages too high or too low to constitute a meaningful constraint on employers. The article compares minimum wages worldwide, proposes several ways of measuring them in developing countries and discusses whether they are effective thresholds in those countries. The second part of the article considers the institutional factors leading countries to set minimum wages at extreme levels. The author concludes that the minimum wage is used as a policy instrument to several ends – wage negotiation, deflation and social dialogue – which results in the absence of a wage floor, weak collective bargaining, or non‐compliance.     

Public–private wage differential and gender gap in Latin America: Spoiled bureaucrats and exploited women?

This paper uses a rich collection of household surveys to investigate the wage differential between the public and private sectors in 13 Latin American countries. It also studies how the sector of employment affects the gender wage gap. Contrary to what is commonly thought, it is found that, in the majority of Latin American countries, there is a premium associated with working in the public sector. It is also found that the premium is often higher for women than for men but that this difference does not compensate for the wide gender gap.     

Explaining the Wage Gap: Intra-Industry Trade, Services Linkages and Falling Transportation Costs

In the debate on globalisation and wage inequality within countries, Heckscher–Ohlin theory has featured prominently, yet fails to take into account that globalisation comprises much more than increased trade between advanced and less-advanced countries. This paper develops a framework that takes better heed of the many aspects of globalisation and thereby addresses a new channel through which globalisation might influence wage inequality. Our results indicate that to understand the impact of globalisation on wage inequality, one needs insight in the nature and stage of globalisation and the relative size of a country.     

The Decomposition of Firm-size Wage Differentials

No completely satisfactory explanation for the persistent and well-documented large-firm wage premium has been found. I use a novel adaptation of the Oaxaca/Blinder wage discrimination model to examine the firm-size wage differential which allows the wage differential to be decomposed into the portions attributable to (1) differences in employee endowments, (2) how the firm values these endowments, and (3) residual differences. Small firms actually pay higher wages based on how they value their workers’ endowments, but this wage premium was overshadowed by the superior endowments of workers in large firms and a residual differential in favor of large firms.
